Momwe nozzle ya galimoto imagwirira ntchito
Mfundo yogwirira ntchito ya nozzle yolowetsa mafuta agalimoto imadalira kwambiri njira yowongolera maginito. Pamene gawo lowongolera injini (ECU) lipereka lamulo, coil yomwe ili mu nozzle imapanga mphamvu ya maginito, yomwe imakoka valavu ya singano ndikulola mafuta kuti afafazidwe kudzera mu nozzle. ECU ikasiya kupereka mphamvu ndipo mphamvu ya maginito ikatha, valavu ya singano imatsekedwanso pansi pa mphamvu ya kasupe wobwerera, ndipo njira yolowetsa mafuta imathetsedwa .
Njira yowongolera zamagetsi
Mphuno yamafuta imayendetsedwa ndi mfundo yamagetsi. Makamaka, ECU ikapereka lamulo, coil yomwe ili mumphuno imapanga mphamvu yamagetsi, imakoka valavu ya singano, ndipo mafuta amathiridwa kudzera mumphuno. ECU ikasiya magetsi, mphamvu yamagetsi imatha, valavu ya singano imatsekedwa ndi kasupe wobwerera, ndipo njira yojambulira mafuta imatha.
Dongosolo lojambulira mafuta
Chotsukira mafuta chimapangitsa mafuta kukhala ndi mphamvu zambiri ndipo chimawathira molondola mu silinda ya injini. Malinga ndi njira zosiyanasiyana zobayira, chingagawidwe m'magulu awiri: single point electric injection ndi multi-point electric injection. Single-point EFI idapangidwa kuti iike injector pamalo a carburetor, pomwe multi-point EFI imayika injector imodzi paipi yolowera ya silinda iliyonse kuti ilamulire bwino injection ya mafuta.
Nozzle ya galimoto, yomwe imadziwikanso kuti nozzle yopangira mafuta, ndi gawo lofunika kwambiri la makina opangira mafuta a injini ya galimoto. Ntchito yake yayikulu ndikulowetsa mafuta mu silinda, kusakaniza ndi mpweya ndikuwotcha kuti ipange mphamvu. Nozzle yopangira mafuta imatsimikizira kuti injini ikugwira ntchito bwino poyang'anira nthawi ndi kuchuluka kwa mafuta omwe amaperekedwa.
Mfundo yogwirira ntchito ya nozzle imachitika kudzera mu valavu ya solenoid. Pamene coil yamagetsi yapatsidwa mphamvu, kuyamwa kumapangidwa, valavu ya singano imayamwa, dzenje lopopera limatsegulidwa, ndipo mafuta amathiridwa mofulumira kwambiri kudzera mu mpata wa annular pakati pa singano ya shaft ndi dzenje lopopera pamutu pa valavu ya singano, ndikupanga chifunga, chomwe chimapangitsa kuti kuyaka kwathunthu kuyake. Kuchuluka kwa mafuta a nozzle yopopera mafuta ndi chinthu chofunikira kwambiri podziwa chiŵerengero cha mpweya ndi mafuta a injini ya galimoto. Ngati nozzle yopopera mafuta yatsekedwa ndi kuchulukana kwa kaboni, izi zimapangitsa kuti injini igwedezeke komanso mphamvu yoyendetsa isakwane.
Chifukwa chake, ndikofunikira kuyeretsa nozzle nthawi zonse. Nthawi zonse, tikulimbikitsidwa kuti ngati galimoto ili bwino komanso mafuta ake ali abwino, nozzle ya mafuta iyenera kutsukidwa makilomita 40,000-60,000 aliwonse. Ngati nozzle ya jakisoni yapezeka kuti yatsekeka, iyenera kutsukidwa nthawi yomweyo kuti injini isawonongeke kwambiri.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&750 zolandiridwa kugula.
